Beschreibung
This mineral tank is the pressure vessel that holds the media bed in a whole-house water treatment system. Available in a range of sizes from 120,000 to 1,200,000 grain capacity, it supports various commercial and large residential softening needs by providing a durable, reliable container for water conditioning media.
The problem you face with your water treatment setup
If you have a whole-house water softener or filtration system, you likely depend on a mineral tank to hold the media that treats your water. Over time, these tanks face pressure and wear from constant water flow. A tank that fails or leaks can interrupt your water treatment and cause costly downtime or damage. You might notice problems like water discoloration, reduced flow, or even pressure loss that points to an aging or unsuitable tank.
Why this happens
The mineral tank is a pressure vessel designed to contain the media bed—whether resin beads for softening or other treatment media—and withstand water pressure continuously. If the tank is undersized, poorly constructed, or has been in use for years, it may weaken or corrode. The right tank matches your water conditions and demand, ensuring the media stays contained and the system operates smoothly.
What it’s costing you to leave it as is
Using a mineral tank that's too small or failing means your system can’t treat water effectively. Scale buildup may return, appliances work harder, and you’ll spend more time cleaning fixtures and removing stains. If the tank leaks or ruptures, it could require emergency repairs, disrupting your water treatment and potentially causing water damage.
How this mineral tank solves the problem
This tank provides a sturdy, pressurized container for your water treatment media to function properly. Its construction is designed to safely hold the media bed under water pressure, allowing the treatment process—such as ion exchange in softening—to take place continuously and efficiently. The tank safeguards your system’s operation by ensuring the media stays in place and the water flows as needed.
What this tank handles
Available in eight sizes, this mineral tank line ranges from 120,000 to 1,200,000 grain capacity. That means you can select a tank that matches your household or facility’s water demand and mineral load. Smaller sizes suit moderate residential or small commercial needs, while the larger tanks handle high-demand applications like multi-unit housing or commercial buildings. Its design supports continuous use and high flow rates, with options to pair tanks for twin or alternating setups, ensuring uninterrupted soft water supply.
What you actually get
Each mineral tank comes with a lifetime warranty on the pressure vessel itself, ensuring long-term durability. The control valve and electronics, which direct the treatment cycles, have their manufacturer warranties and are confirmed when your system is sized for your water. The exact tank configuration depends on your water conditions and treatment requirements.
Is this the right size for you?
The range of sizes means there’s a tank suited for medium to very large water softening or filtration needs. If your water use and hardness are moderate, the lower grain capacities will suffice. For large facilities or heavy mineral loads, the higher capacities ensure the media bed lasts longer between regenerations. Choosing the right size depends on your water test results and daily consumption, which our team will help assess.
Living with this tank
Maintenance is mostly about periodic media replacement and ensuring the control valve operates correctly. The tank itself rarely requires service thanks to its robust construction and lifetime warranty. Your plumber will handle installation and any ongoing checks. Depending on water conditions, some media beds last several years before they need replacement or regeneration cycles.
What this tank won’t do
This mineral tank is not a standalone water softener or filter. It’s the container that holds the media but does not itself treat the water. You’ll need the matching control valve, resin, or other media configured for your specific water problem. It won’t address issues like bacteria, sediment, or chemical contaminants unless paired with the correct treatment media and system.
